MATERIALS
Porous plastic components can be produced from a variety of polymers, including engineered plastics. Component form and function drive the material selection process.
Polyethylene (PE)
is non-toxic, odorless, tasteless. Many grades are FDA compliant for use in food processing and handling equipment. When sintered, its color is white. Functional temperature range is: -26° to 180° F.
Polypropylene (PP)
PP offers a combination of outstanding physical, mechanical, and thermal properties. It has a high corrosion resistance. It has good dimensional stability and surface hardness. It has the highest heat resistance of all the polyolefins. Color is translucent white. Temperature range: 32° to 210° F
Polytetrafluoroethylene (PTFE)
PTFE will operate in the harshest chemical environments. It is non-toxic, non-allergenic, non-conductive, and can be easily cleaned. It has a very low coefficient of friction (very slippery). Color is white. Temperature range -350° to 500° F.
Polyvinylidene Fluoride (PVDF)
PVDF is a specialty plastic material in the fluoropolymer family; it has the highest purity, strength, and resistance to solvents, acids, bases and heat.
Ethylene-vinyl Acetate (EVA)
EVA is flexible (rubbery), with good low temperature flexibility (-70'C). It has a good chemical resistance and a high friction coefficient. It has a white to transparent appearance
Polyamide (PA)
PA-Nylon has excellent surface finish, strength, and stiffness. It is chemically resistant to hydrocarbons.
